A fresh corn preservation technology under normal temperature without freezing, no salting, no vacuum packaging, and no drying (drying) was successfully tested by Kangzhuang New Resource Technology Research Institute of Yutian County, Hebei Province. At the end of August of this year, the experimental institute had stored more than 5,000 fresh and tender maize. As of the end of March this year, it was fresh and tender, and the cost per ear of corn was only about 3 cents. The method of preserving fresh corn overcomes the freezing method and other room temperature preservation methods for keeping corn fresh in high cost, complicated operation, poor preservation effect, poor taste, and other shortcomings. When operating, only the tender rice is soaked in pre-prepared fresh liquid In the middle, you can achieve the purpose of long-term preservation, the preservation period of up to 8 months. Preservation solution preparation is the biological mechanism of the aging quality of tender corn based on the scientific research personnel of the Kangzhuang Institute of New Resources Technology, scientific selection of natural anti-oxidant preservatives, broad-spectrum bacteriostatic antibacterial agents, which have a strong inhibitory effect on the activity of corn enzymes. Synergist and other compounded. Under the comprehensive action of various components of fresh-keeping liquid, tender corn can maintain its original fresh physiological state for a long time under normal temperature environment, without moldy rot. In addition, the experiment proves that this technology is also suitable for fresh preservation of watermelon and various rare vegetables, and the effect is very good. First, the technical principle of tender corn is sweet and delicious, nutritious, everyone loves to eat. However, the tender corn picking season coincides with a vigorous growth period, and it is very difficult to store and preserve. At present, the tender corn that is sold across the seasons in the market is basically frozen and stored for preservation. The one-time equipment has large investment, high cost, poor taste and difficulty in popularization and promotion. Although in recent years some units have also promoted several methods of preservation of tender corn at room temperature, such as drying (drying) - rehydration preservation, sterilization (ozone generator) preservation, but the operation is complex, the preservation period is short, the effect not ideal. This article describes the tender corn fresh-keeping technology, without freezing, no drying, no daily management, as long as the picking of fresh corn after pre-prepared fresh liquid, you can achieve long-term storage and preservation purposes, preservation The period of up to 8 months, pure taste, quality fresh as ever, and preservation costs only about 3 cents per spike. This method does not require equipment investment in corn preservation, simple and easy operation, easy procurement of raw materials and cheap, very popularized and promoted value. Second, the process of tender corn pretreatment → fresh liquid cabinet → finished product (listed) Third, preservation solution formula and preparation method 1 formula: sodium benzoate salt 0.1% ~ 0.3%, organic acid 0.2%, inositol hexaphosphate 0 .l%, Vitamin C 0.1%, water balance. 2 Preparation method: First, according to the formula, the sodium benzoate salt and organic acid are dissolved in water and heated to boiling. After cooling, human inositol hexaphosphate and vitamin C are added. After mixing, the corn preservation liquid is used. Fourth, the operating points 1. Raw material harvesting should be selected just full of grain and not solidified, the head of the stamens are not dry and tender corn (ie 7 mature state). 2. Preservation solution should be removed before soaking. Stamens, rinse with water. After being collected, it must be processed on the same day. Otherwise, the quality of aging will have no fresh-keeping value. 3. The freshness of the preservative should be equal to that of the non-prepared corn (the ratio of the weight of the preservative to the corn is 2:3). 4. Fresh-keeping storage containers can use plastic buckets, large cylinders or concrete pools. Wash and sterilize before use. 5 Storage Preservation of fresh corn should be filled with containers as much as possible, covered and sealed to reduce air oxidation. 6. The ingredients in the fresh-keeping liquid are all food additives and can be purchased from food additive stores around the world. 7 Such as in the fresh liquid formula supplemented with different flavors of food flavor, but also processed into a variety of different flavors of fruit-type fresh-keeping corn, a higher value. 8. This method preserves fresh and tender corn, generally operates in early summer and is best listed before and after the Spring Festival.
ETR has independently developed an integrated vacuum pump unit composed of a water-ring vacuum pump, a gas-water separator, a vacuum solenoid valve, pipe fittings and an electrical control system. It is a simple, safe and reliable device that continuously serves the wards all day long, without occupying the ward space. The negative pressure is sourced from the vacuum pump unit.
